Protecting Oaks from Ambrosia Beetles: Identify the Species First

Native ambrosia beetles attack dead wood; non-native (Asian) species kill living trees like oak, maple, crape myrtle, redbud. If Asian ambrosia beetles are confirmed nearby, hire a tree company experienced in control, or spray susceptible tree bark with bifenthrin or permethrin in early March and early April annually.
